Abstract:
본 발명은 블라스팅 박리를 이용한 범퍼 커버의 재활용 방법에 관한 것으로서, 보다 구체적으로는 블라스팅 도막 제거 챔버를 이용하여 자동차 범퍼 커버의 도장막을 제거하고 이를 압출 및 사출 성형용 플라스틱 수지로 재활용하기 위한 공정 및 그 방법에 관한 것이다. 본 발명에 따른 블라스팅 박리법을 사용한 방법은 기존의 화학적 박리법이나 범퍼 커버용 신재료를 이용하는 방법과 비교해서 동등 이상의 기계적 물성 확보가 가능하고, 외관특성에 있어서도 신재료 수준의 품질을 확보할 수 있다. 또한, 기존의 화학적 박리법이나 모래 이용 분사법에 비해서 도막 및 도금 제거 효율이 우수하고 매개체를 재활용할 수 있으므로 경제적으로도 매우 유리하다.
Abstract:
PURPOSE: Recycling method and system of waste bumper fascia are provided to convert the waste bumper fascia into a recyclable material. CONSTITUTION: A roll compressor(10) compresses waste bumper separated from a car body. A detaching unit(20) detaches a paint film from a waste bumper surface of a temperature-increasing state by the roll compression. The detaching unit scratches the waste bumper surface using a brush. A residue remover(30) removes detached paint film residue from the waste bumper surface. A grinder(40) grinds a paint film-removed waste bumper. A storage unit(50) stores the grinded recycling material.

Abstract:
PURPOSE: An additive for recycling air bag fabrics is provided to impart compatibility to a nylon cloth of silicon rubber and air bag fabrics using only compatibilizer without an additional process. CONSTITUTION: An additive for recycling air bag fabrics uses a compatibilizer which is at least one kind of a styrene-maleic acid anhydride copolymer, a maleic acid anhydride grafted with EPDM(ethylene propylene rubber), and maleic acid grafted with an amorphous ethylene copolymer. A resin composition using the air bag fabrics comprises 95.0-99.7 weight% of recycled chips and 0.3-5.0 weight% of compatibilizer.
